(
*
: Preset)
H-FREQUENCY (Horizontal oscillation frequency)
Switches horizontal frequency.
(00): 28.125 kHz
Horizontal frequency become 31.25 kHz when H-FREQUENCY
=
(01) and V-FREQUENCY
=
(001)
HD1/VD1-OUT SW (HD1/VD1 output switch)
Switches output from pin 16/28. When set to 00, 01, or 10, outputs HD/VD without synchronization.
When set to 11, outputs HD/VD from the sync circuit. (Note) Synchronized VD width will change, when
HD PHASE will be changed.
*
(00): HD1/VD1
(01): HD2/VD2
(10): HD3/VD3
HD2/VD2-OUT SW (HD2/VD2 output switch)
Switches output from pin 19/29. When set to 00, 01, or 10, outputs HD/VD without synchronization.
When set to 11, outputs HD/VD from the sync circuit. (Note) Synchronized VD width will change, when
HD PHASE will be changed.
*
(00): HD1/VD1
(01): HD2/VD2
(10): HD3/VD3
SEPA LEVEL (Sync separation level switch)
Switches sync separation level of pin 24/26. Set values are the levels from sync tip. Sync separation level
is changed according to the ratio of H-SYNC width during 1H period. (Note) This IC doesn’t have the
sync-separation circuit for non-standard signals like weak strength signal, ghost signal and so on.
*
(00): 10IRE
(01): 15IRE
(10): 20IRE
DAC1 (DAC1 control)
Controls 2-bit DAC (pin 12).
(00): 1 V
(01): 3 V
*
(10): 5 V
DAC2 (DAC2 control)
Controls 2-bit DAC (pin 25).
*
(00): 1 V
(01): 3 V
(10): 5 V
DAC3 (DAC3 control)
Controls open collector 1-bit DAC (pin 30).
*
(0): OPEN (HIGH)
(1): ON (LOW)
TEST (Test mode)
Switches DAC1, 2, and 3 outputs. Also used to test IC for shipping.
*
(0): DAC outputs are used as DAC.
(1): DAC1 outputs V. SYNC to the frequency counter.
DAC2 outputs H. SYNC or C. SYNC to the frequency counter.
DAC3 outputs IC test pulse for shipping.
(01): 31.5 kHz (31.25 kHz)
*
(10): 33.75 kHz
(11): 45 kHz
(11): Synchronized HD/VD
(11): Synchronized HD/VD
(11): 25IRE (at 1125I/60)
(11): 7 V
(11): 7 V
